Heroes and villains unite for New York Comic Con

From heroes like Captain America to villains like The Joker, people at New York Comic Con put aside their differences to share a love of comics.

At the preview night for New York Comic Con, heroes like Captain America and Inspector Gadget rubbed elbows with villains such as The Joker and Skeletor.

But far from the latest battleground in the epic fight of good versus evil, the convention—those masked adventurers say—is a place to revel in a shared excitement for comics and all things inspired by them. Their goals: Get a sneak peek at upcoming releases, meet favorite artists and celebrities and show off costumes that took, in some cases, months of hard work.

Last year, the four-day con attracted more than 116,000 attendees, according to organizers. What's the draw this year? We'll let the fans tell you, in their own words.

America has the highest incarceration rate in the world, and that opens up the door for companies to have a captive market -- literally. One of those companies is JPay, which provides electronic money transfers and other services to about 70 percent of state prisons. But in order to get that lucrative state prison contract, the state takes a commission as well. Critics argue all the costs are passed down to families and inmates, often burdening them financially.
